Things To Note
- To open more than one session of StudyTRAX, a new session must be used. DO NOT use another tab or Ctrl-N to open a new browser.
- Plan the variables that will be Universal Subject Variables. These variables are used across all projects. Subjects enrolled in subsequent projects will not need their universal subject variables re-entered. Individual projects can opt out of viewing any of the Universal Subject Variables.
- A variable group that will be collected on multiple occurrences only needs to be created one time. The intervals determine the data collection schedule and the same variable group can be collected on multiple intervals.
- When creating a variable, be sure the variable type is correct. The variable type cannot be changed once data is collected. A common error is to use a text type variable instead of a numeric type variable.
- Subject Report Templates
- It is a good practice to keep a backup that works.
- Add a little at a time and test the report (if no subjects are entered in the project, enter a test subject, and select view in Subject Overview on the Reports tab in Details view).
- Change between design mode and html mode through the tabs at the bottom of the report content section.
- Optionally, formatting can be done in html mode instead of design mode.
- When copying a subject report, copy from html mode and paste into html mode.
- Always create the simplest project configuration possible. If you are not sure that your project requires a feature, do not enable the feature as most features can be enabled later. Once a feature is enabled and data is entered, it may not be able to be disabled. However, Randomization and Screening cannot be enabled once subjects are enrolled in the project.
- Run test subjects through the encounters/data entry screens prior to collecting data for real subjects.
- If a project is giving an error, isolate the variable group causing the error by adding one variable group at a time until the problem appears. Within a variable group, add one or several variables at a time until the problem appears. A test project can be used for trouble shooting; if a project license key is required, email support@sciencetrax.com to request a test project license key. An error in the project can be the result of a JavaScript error or an html error.
- JavaScript is case sensitive, thus ensure the case is correct.
- Placing // in JavaScript code indicates a comment will follow.
- To comment several lines, place /* at the beginning and */ at the end.
- Place a # in front of a Variable Code when referencing the variable.
- Changing a variables' code automatically changes its code in the JavaScript of the variable dependency.
